Studio equipment

My family and I recently visited a professional photographer, for a portrait session.

The results were quite good, but I'm sure I could get somewhere close to the results myself, with a little bit of knowledge, practice and effort.

The studio was white walled and floored, and had a couple of lighting umbrellas.... and obviously an expensive camera & lenses.

I want to know what would be the best budget type of equipment I could buy to get this type of equipment. I have seen the white background sheets for sale, but unsure which umbrellas, and wattage / temperature of lighting....
